DCO can mean several different things....it can mean a digital clock signal 
sent to analog circuits to create the waveform (I think the Juno works like 
this), it can mean digital waves that come from wavetables( PPG), or it can 
mean the waves are digitally synthesized within the chip (SID chip).  I 
think the Poly 800 is the last type.  As far as I know, the chip is only 
capable of making square waves so the Poly 800 only roughly approximates the 
saw wave.  They sure cut a lot of corners but the result is a pretty 
interesting synth.  Also I think the DCO chip was also used in some 80's 
arcade games.
